I've followed the guidelines here: https://github.com/zalando-incubator/kube-ingress-aws-controller/blob/master/deploy/kops.md but kube-ingress-aws-controller restarts every 2-10 minutes.
When I follow the log of the pod I get this error "EC2MetadataError: failed to make EC2Metadata request"
I have rebuilt the cluster and deleted it several times and cannot create the load balancer or target groups - although I have in the past. One of our clusters is still running so I have compared it in detail - and have got no differences except in the name.

We are blocked. This is our development environment. The instances have public & private IPs and the VPCs & SGs have been generated correctly.

Where should I look now please?
